in some way the guy in charge of Dengeki said some like: "Shakugan main story finished", you ready know new manga was release with a precuel??, if we look they could try: 1.before Shana, like the new manga and 2.Hope & Future story line.

Sorry,are you talking about Eternal song ?

...

So about S3 , only Future and hope are set after the anime... the rest of the stories are a prequel...

I'd really like to read Friagne the Hunter IV , there seems to be a lot of useful information...

About the picture where shana-yuuji-yoshida-ike are eating together,which story is that ?
